Air Ducting Welding Pins With Insulation, 3.4mmx22mm Cupped Base Welding Pin
>>> Introduction of welding pins
Each point is precisely formed to provide optimum weld current and
each cap and shank assembly is securely swaged and centered
so that pins will feed without jamming,
even in older welders. In addition, PowerPoint Weld Pins may be
shipped in plastic buckets to eliminate shipping damage. The result
is continuous production without the expense
of clearing track jams or refastening where other pins fail.

>>>Technical Data of insulated cup head pins
| Temperature Range | PowerPoint Weld Pins function properly over normally accepted
operating range of temperatures of 32 oF to 250 oF and are not
adversely affected at temperatures of 0 oF to 550 oF. |
| Vibration | PowerPoint Weld Pins will not fatigue or be physically affected by
vibrations normally found in high velocity air handling systems. |
| Environmentally Safe | When used as intended, PowerPoint Weld Pins are non-toxic and safe
as defined by current Federal Standards. |
Application
1. Cupped head welding pins is a insulation fastener which is used
to fasten the insulation materials to sheet metal
of air duct, other heating, ventilating or air conditioning.
2. A fabricated part made up of a weld pin and a staked on
retaining washer,it is usually applied with a capacitor
discharge stud welder.
3. The method of application is to place the insulation onto a
metal surface, push the Cup Head weld pin through the insulation,
and
weld affix (mount) the entire fabrication
in one step. Now it is widely accepted as labor saving fasteners in the thermal and acoustical insulation markets for use in
industrial
and commercial applications.

Diamond Points - Forged diamond point design creates an extremely sharp point
that cleanly pierces the toughest duct liner for the best
contact and weld current.
Better Plating - Zinc and chromate dipped, PowerPoint Weld Pins exceed SMACNA
corrosion resistance standards and give a more
professional appearance.
Consistent Feeding - Precisely centered assembly of shanks and caps, along with a
smoother finish reduces feeding problems in tracks
of automatic equipment.
Retaining Cap - The beveled edge retaining cap is sufficient in size and design to
depress the surface of the insulation without tearing or
cutting. The cap does not protrude into the air stream, preventing noise or interference with air
movement in the duct.
